New Engine Design Doubles Fuel Efficiency

[myshtern]

This seems like a pretty cool advancement of the basic 4-stroke engine. It's like a radial engine only the opposing rods are connected so a power stroke on one side makes the compression or exhaust stroke on the other side thus little to no energy is wasted transferring it through a crankshaft. Or at least that's what I got from it.

The article says, "This isn’t some hoax… They have a prototype which has been attached to an actual vehicle and independently tested to substantiate their claims." But then it doesnt actually link or reference to the independent test...

The first one is pictures and the second link is the test results. You can click within the second page for the full results in PDF format.

would be sick, 1/2 the price on gas

the engine design is purty sick

Sounds like a pretty cool idea! We probally wont see it for another 15 years or something!

The idea is simple enough, get rid of as many weak points and parasitic losses as you can = improve efficiency. No crankshaft, wristpins, solid connection of 2 pistons with a non rotating connecting rod. Rotation conversion via a cam instead of a crank. Simple ideas like this make you slap yourself and say "why didn't I think of that." Just imagine adding a turbo to utilize the heat energy on this thing.

hmm, sounds like a good idea, but so does the rotary. Have to wait and see where it goes.

Agreed. I'd like to see the "roller" seal designs advanced into the rotory. But at this point, that revtec design seems much more feasable.

I'd like to see that revtec design oriented for big rig turbo diesel use. Think about the torque possibilities, along with the possible fuel savings! :eek:

Thats pretty damn cool, I must say

Glad to see that design actually see the light of day. We studied that design in physics back in (dare i say), 1991. :D

it dont look turbo freindly lol and a pain to work on
